[Report of a case--adenoma of the middle ear].
A 44-year-old female with adenoma of the middle ear was reported. Her chief complaint was hearing loss in the right ear. A white mass inside the right external auditory canal was observed. Audiometry revealed a combined deafness with the average hearing of 38.3 dB for the speech frequencies. The study by high resolution X-ray CT revealed a density area as like as a soft mass in the tympanic cavity. A tumor existing mainly in the hypotympanum was surgically removed and modified type III tympanoplasty by interposing the malleus head as an autograft as a columella was done. Postoperative course was good and the average hearing improved slightly to 30 dB. Histopathological study with stains of HE, PAS, mucicarmin, colloid iron, NSE and S-100 protein showed adenoma of the middle ear.
